The Lowdown
Alright, let’s do that again in feet and miles per hour for you landlocked imperial heads.
Alright, Rusty here. Let’s talk about what’s cookin’ at Jaconé.
Right off the bat, this spot is gonna be pumping, especially for the crew who can handle some serious juice. The water is sittin’ at about 73°F, which is pretty much what you’d expect for this time of year—nothing weird going on there.
We start off with a solid pulse. Tuesday morning (Aug 25) is kicking things off with 8ft of south swell, a strong 14-second period, and east winds just holding it open. That’s heavy, powerful water—definitely for experienced surfers only. This energy is chunky, with a combined swell energy reading of 2698, and it stays up for the afternoon and into Wednesday morning, where the wind drops to glass early. Wednesday the 26th morning is glassy with 7ft of south swell and a 12-second period – a real treat for the early crew.
Thursday the 27th keeps the run alive with 8ft of south swell and bone-glass conditions in the morning. That’s as clean as it gets. Friday the 28th drops off a touch but still offers some fun 4ft waves with a nice offshore breeze from the NE in the morning.
The weekend is a bit mixed. Saturday the 29th and Sunday the 30th have some punchy short-period ENE swell in the mornings—6ft—with clean offshore winds and a combined energy around 600. It’s not the same quality as the first few days, but it’s still rideable.
Now, there’s a real lull from Sunday afternoon through to about Thursday the 3rd of September. Waves get small and messy. You’re lookin’ at a solid 4-day gap where there’s nothing worth paddling out for. The energy drops to double digits or low triple digits, and the swell direction gets all over the shop.
But hold tight, because the real standout window is shaping up around Saturday the 5th of September. That morning, we’ve got 7ft of short-period swell from the south with a clean NE offshore. The afternoon, though, swells to 10ft from the south with a 12-second period and combined energy of 2937. That’s a lot of water—too big for most surfers, but a proper adrenaline hit for the experts.
Sunday the 6th of September is another gem: 8ft of long-period south swell with 1741 energy and light offshore NE winds. Same for the afternoon: 7ft, glassy conditions. That’s a solid 48-hour window of quality, powerful surf for the experienced crew.
The second week does taper off. By Monday the 7th, the wind turns cross-onshore and waves get sloppy, and the rest of the week stays small and ordinary.
Best on offer: Without a doubt, Wednesday morning Aug 26 is a standout—7ft of south swell with glassy conditions and a 12-second period. That’s clean, powerful, and you’ve got the place to yourself if you’re early. For the big-wave crew, Saturday afternoon Sep 5 is the one, but that’s a long-range call and could shift.
Overall, first week is a ripper for strong intermediates and experts. Crowds are possible here, so get in early. The second week has a few promising windows, especially around Sep 5-6, but nothing solid yet.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
